A police officer has been seriously injured after being hit by a stolen PSNI car.
The Police Service of Northern Ireland (PSNI) has begun an attempted murder investigation, saying the act had the potential to cause "fatal injuries".
During the incident in Downpatrick early on Sunday morning, the officer fired a shot.
Around 4.45am, a vehicle failed to stop for police in the Fountain Street area and was later found in the Ballymote Walk area.
A man was then seen running from the vehicle and a foot pursuit ensued towards the Colmcille Road.
PSNI Assistant Chief Constable Melanie Jones said: "As officers returned to their police car, someone was in the driver's seat - driving erratically and directly towards an officer.
"The officer discharged one round from his firearm.
"The officer was struck by the vehicle - causing serious injuries. The vehicle was subsequently abandoned a short time later. The suspect made off from the scene."
A 27-year-old man has been arrested on suspicion of attempted murder.
The police vehicle, officer's weapon and ammunition have all been recovered and removed for forensic examination.
The Police Ombudsman confirmed it had been notified of the firing of a round, and its investigators attended the scene.

Assistant Chief Constable Jones continued: "As is standard procedure when a police firearm is drawn, the Police Ombudsman for Northern Ireland has been informed - and their enquiries are ongoing.
"Officers put themselves on the front line to help keep people safe - they do not deserve to be assaulted for simply doing their job, and today's incident is a stark reminder of the dangers they face.
"Our thoughts are with the officer as he receives ongoing medical treatment today for his injuries in hospital. And we will continue to support him and his family."
